PEORIA, Ill. -- Peoria Zoo officials said Wednesday that their female tiger was died of blastomycosis, a fungal infection.
The Zoo's female tiger, Kyra, died on August 18 after falling ill and not responding to treatment. Kyra came to Peoria in 2006 and gave birth to four cubs in June 2012.
Blastomycosis is caused by a fungus that can be found in soils throughout the world.
In the United States, the fungus is native and common in the Midwest and Southeast. Lung infections occur when fungal spores are inhaled.
Zoo officials say no other tigers at the Zoo have demonstrated any symptoms and that more tests and physical exams will be performed soon.
